On April 19, 2009, Viloria moved back down to junior flyweight to challenge Mexican Ulises "Archie" Solís for the IBF Junior Flyweight title.

The official bout stoppage was a KO 2:56 into the 11th round. The fight was held at Araneta Coliseum in the Philippines, site of the Thrilla in Manila, as the co-main event of the Donaire-Martinez fight.

On September 6, 2009, Viloria, who was in attendance at the World Cup of Pool, was chosen to perform the ceremonial break shot before the start of the final match. Because he never played pocket billiards before, Viloria miscued on his first attempt but achieved the shot on his second.

On April 14, 2007, he fought Edgar Sosa for the vacant WBC Light Flyweight title but lost via majority decision.

He successfully defended it once on February 18, 2006 against José Antonio Aguirre (boxer) and was undefeated in 20 bouts. Viloria's unbeaten streak ended when he was dethroned by Mexican Omar Niño Romero on August 10, 2006.

In a rematch held on November 18, 2006 at Las Vegas, Romero held on to his title with a controversial majority draw decision, with Viloria knocking down Romero twice during the fight.
